Check if a string has white space

Question

I\'m trying to check if a string has white space. I found this function but it doesn\'t seem to be working:

function hasWhiteSpace(s) 
{

Your regex won't match anything, as it is. You definitely need to remove the quotes -- the "/" characters are sufficient.

/^\s+$/ is checking whether the string is ALL whitespace:

• ^ matches the start of the string.
• \s+ means at least 1, possibly more, spaces.
• $ matches the end of the string.

Try replacing the regex with /\s/ (and no quotes)
